Abstract
Objective
We reviewed our experience in surgical treatment of craniopharyngiomas. Surgical treatment of craniopharyngiomas in children represents a challenge for neurosurgeons because it presents a different set of surgical problems. Results are controversial and debates concerning strategies to ameliorate the rate of success and to decrease the rate of morbidity and mortality are ongoing. Post-surgical quality of life is related to the anatomical relationship between the hypothalamic region, vascular structures and optic pathways.
Discussion
From 1985 to 2004, 60 children (age range, 4 months to 18 years) were treated in our institution. Since 1987, all patients were studied with pre- and postoperative MRI. Two groups of patients were distinguished: a group of 36 patients treated with surgical direct surgery; a second group of 24 patients treated only with intracystic chemotherapy with bleomycin (18 patients) or associated with surgery (six patients). In the first group, the removal of lesion was total in 74% of cases. Two patients died in the early postoperative period and two more died later (early mortality of 5% and late mortality of 11%). All patients presented ante-pituitary insufficiency and diabetes insipidus, which required substitutive treatment. Twenty-two patients presented with visual problems, including amaurosis in two cases. In the group treated with bleomycin, 18 patients presented a primary cystic or a mixed form of craniopharyngioma and six patients showed a cystic recurrence. Eighteen patients were treated with bleomycin only. The dose used varied from 30 mg to a maximal dose of 150 mg, with a middle dose of 60 mg in the large majority of cases. In this group, the cyst disappeared in 12 patients and reduced to 30% of its initial volume, and stabilization of the lesion was achieved in the other six patients. Only 11 patients presented partial endocrine insufficiency. Of the 18 patients, 16 were of school age, 14 of whom were following a normal educational program and two an assisted program. No mortality was reported.
Conclusion
Our experience showed that in the group treated with intracystic chemotherapy alone, results were better with a low rate of morbidity and mortality. Endocrinological, visual and neuropsychological evaluations were also correlated with better outcome. In cases of cystic craniopharyngiomas, we considered bleomycin as the treatment of choice. For solid forms or for cases resistant to intracystic chemotherapy with bleomycin, direct surgery has to be proposed.
